To all whom it may concern: c

Be it known that we, ERNEST A. OHEG- WIDDEN and THOMAS ROOT, citizens of the United States, residing at Vest Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Devices for Operating Shutters, of which the following is a specification.

This invention has for its object an improved apparatus for working shutters, and the invention consists in certain constructions, arrangements and combinations of the parts that will enable the shutters to be opened and closed from the inside of a building, Without the necessity of raising the window sashes and leaning out of the window.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a view of the inner side of the window sash or frame at which two of our improved shutter operatin devices are located; Fig. 2 is a vertica sectional view through the window, Fig. 3 is a perspective view of the outer side of the window with the invention applied Fig. 4 is an enlarged transverse sectional view of the apparatus; and, Fig. 5 is a detail perspective view of the latch plate and its kee er.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Our improved shutter working apparatus comprises a crank shaft 1 which is provided at its upper end with a horizontally disposed crank 2 having an upwardly turned extremity accommodated in a guide plate 3 which is provided with ears or the like, as shown, so that it may be screwed or otherwise attached to the outer side of a shutter near the lower edge thereof.

The crank shaft. 1 is journaled to turn about a vertical axis in the upper and lower horizontally disposed members of a bracket 4 which is screwed or otherwise secured to the Outer side of a window sill, as shown. The shaft 1 carries a bevel pinion 5 which meshes with a similar pinion 6 on the outer end of the shaft 7. The shaft 7 is ournaled in the vertical member of the bracket 4, as clearly illustrated in the drawings and eX- tends inwardly to the inner side of the room. It is provided on its inner end with a handle or knob 8 of any desired design or ornamentation intended to be grasped by the operator when actuating the apparatus.

A locking plate orkeeper 9 in the form of a disk is screwed or otherwise secured to the inner side of the window sill and vencircles the actuating shaft 7, and said keeper is formed with a circular series of apertures 9a intended to receive the locking pins 10 roj ected from the outer face of the latch p ate 11. Said latch plate is formed at diametrically opposite points with outstanding ears 11a by which the o erator may slide the latch plate backward y on the shaft 7, against the tension of the spring 12 that encircles the shaft. It is to be understood that the latch plate 11 is splined or similarly mounted on the shaft 7 so that it may slide longitudinally thereon, but be held to turn therewith. It is to be noted that the latch plate 11 with its ears 11at is so arranged with respect to the knob 8 that the two together wil form an effective hand-hold in manipulating the shaft 7 to open or close the shutter. It is also evident that one of our improved shutter operating a paratus may be provided for each shutter o a window.

From the foregoing description in connection with the accompanyin drawings, it will be seen that we have provi ed a very simple durable and efficient construction of apparatus for opening and closing shutters from the inside of a room, it only being necessary for the operator to gras the ears 11 a of the latch plate 11 and pull the latch plate backwardly to disengage it from the kee er 9 and, while still holding to the latch p ate, `turn the shaft 7 in the required direction, with the palm of the hand ressing against and partially surrounding t ie knob 8.

It will be seen that the device is composed of comparatively few parts that may be cheaply manufactured and easily assembled, and that will not be liable to get out of order. When the latch plate 11 is released, its spring 12 will force it outwardly so that its pins 10 will enter the apertures of the keeper 9 and thereby lock the apparatus with the shutter held in the desired osition, either fully open or closed, or parta ly so.

Having thus described the invention, what is claimed as new is:

An apparatus of the character described, com rising a crank shaft, means for operative y connecting said crank shaft with the shutter, an actuating shaft having a driving connection Withthe crank shaft, enf-support"pansive spring encircling the actuating shaft for the shafts, a keeper disk encircling the aoand bearing against the knob and latch plate. tuating shaft and adapted to be secured to the In testimony whereof We aflix out signainner side of a Windcw frane, a handle knob g tures in presence of two Witnesses. 5 ri i ly secured on tie en of the actuating T sligaft, a latch platek having a splined connec- ERNEST A' GHEGWIDDEN F s'] tion With the actuating shaft and arranged 1 THOMAS ROOT' L S'] for locking engagement with the disk7 said Witnesses: latch plate being formed with outstanding CLARENCE F.
